1'0 (ZZZ whom it may concern.-

Be it known that I, JOHN Enms CUTLAN, a subject of the Queen of GreatBritain, residing at 46 Market Square, \Vellingborough, in the county ofNorthampton, England, architect and surveyor, have invented certain newand useful Improvcmentsin Machines for Driving livets or Nails into theSoles of Boots or Shoes, (for which I have received Letters Patent inGreat Britain, No. 7,893, dated May 19, 1884,) of which the following isa specification.

This invention relates to improvements in machines for driving rivets ornails into the soles of boots or shoes, whereby I am enabled to quicklyand regularly drive nails or rivets into either the inner sole or outersole in the mamifactnre of boots or shoes.

In order the better to explain my invention audthe manner of carryingthesameinto practice, I will proceed to describe the same with referenceto the accompanying drawings.

Figure 1 shows a side elevation of my improved macbinc. Fig. 2 shows afront view elevation. Fig. 3 shows enlarged detail view of the grippingdevice for locking the support or rest. Fig. 4 shows enlarged view, inelevation, ofthe nail feeding and driving apparatus. Fig. 5 is atransverse section of the nail-reservoir. Fig. 6 is a plan,partlyinseetion,of the nail'reservoi r and slide for regulating the supply ofnails or rivets.

Similar letters of reference indicate corresponding parts throughout,and for brevity I shall hereinafter refer to both nails and rivets asnails, and similarly to both boots and shoes as boots.

()nthc standard: is mounted the fly-wheel y, as shown, driven by meansof a treadle, .r, and eonuectingrod in, the trcadlc as always be ingbrought into position ready to start the machine, as shown in Fig. 2, bymeans of the spring 90.

On the shaft of the fly-wheel g the toothed wheel 9 is firmlysccured,and this again gears with and drives the second toothed wheel,v, on the main shaft 1;, from which shaft'u the whole of the parts ofthemechanism are driven or actuated as follows: The plunger a (sliding inbracketarms 2' J on the standard 2 and carrying the punch or drivera',fiXed therein) has rcci n'ocatory upward and downward mo tionimparted thereto by means of the connectiug rod or link I), on thecrank-pin c, on the outside of the double cam o, fixed on the shaft 1;.This revolvingcam cgivcs motion to the slide-bar d by means oftheconnecting arm c, on which is mounted theproiection c,which ridesagainst and is actuated by the doublecam surface 0. (See Fig. 4.)

To the upper part of the plunger 11, and free to turn thereon, ismounted the armf, which again is connected by mcansof the forked rod fto the nail-rcservoinf, to which it is secured on centers/"K Fig. 5shows the nail reservoir fflhaving two compartments, f and f, (for twodifferent lengths of nails) each compartment having a slot, f and f",respectively, in the bottom thereof wide enough to allow only thenailshanks to drop through, and in Fig. 6 the nail feeding device isshown, this being a plate. f]. having a slot, g',(si milar to the slotsand f.) down which the nails are fed from one of the said slotsf andf",either of which can be brought opposite the slot g by the catch g, whilethe nails are prevented from coming out of the slot out of use by thestop or catch 1/, held in position by thesprings y.

The slide-bar d has fixed thereon the slotted plate or slide it,(advantageously formed in two parts, as shown in Fig. 6,) having thefeedslot i, which, by the action of the cam 0, permits one nail at atime to pass from the groove or slot y into the tube or conductor 0,down which it falls into the holoj, immediately under the punch ordriver a. This hole is formed in the spring catches I; and I, which aremounted on axes It" and Z, and arev forced to Openoutward by the drivera coming down, but normally kept closed together by the spring M, asshown in Fig. 4, the fecd'tube o and the parts I. andl bcingdivided andmade so as to open together on hinges o o' for convcniencc in cl auingout or repairs.

On the shaft c, Fig. l, is also mounted an eccentric, p,whicb,by meansof the connectingrod 1) and arm q, Fig. 2, causes the partial revolutionof the axis a, having on the end thereof the toothed wheel 11, whichgears with and revolves the feed-regulating wheel 8, mounted on thesupport a, which support is also adjustable by means of the regulatingscrew s.

On the shaft 1) is also mounted a second eccentric, it, (see Fig. 3,)with a connecting-rod, t attached to a crank-arm, t, (with a spring, 1'.inserted and combined therewith,) for gripping and firmly holding theupright pin t, which travels through its otherend, I, this pin it at itslower end resting against thelevcrbar I, which forms the support for therest a", upon which the work is laid.

The operation of the machine is as follows: Referring to Fig. 1, thework is placed on the rest a by depressing the lever-bar or support 1.",which is t'ulcrumed at f, and at its other end, t, presses up the rod tand springthereon, as by thus depressing the lever arm the rest a dropsdown therewith and leaves space to lay the soleor other work on therest. The lever-arm I." is then released and the reaction of the springon the rod 1 presses the arm i" up again and with it the rest a. Themachine is now put in motion,and at each revolution the plunger a ismoved up and down. This also, by means of the forked arm f, rocks thenailreservoirf (which is hinged to the plate g so as to cause some ofthe nail-shanks to drop through the slot] orf, and thence pass into theslotgin plateg. The slide it is then moved across by the slide-bar (l,actuated by the cam c, and the slot i in the slide h, Fig. 6, as it ismoved across, allows only one nail to pass down and upon the bottom ofthe slot t, coming over slot 5 This nail then drops down the tube orpassage 0 and falls with its point downward into the hole j, directlyunder the driver a. Atthis moment, before the driver comes down onto thenail, the ecccntrict, Fig. 3, forces down the arm 1 and firmly grips theupright rod t at the point t and holds the same rigidly. Thus the lowerend thereof offers a firm resistance to thelever-armt, which thereforemakes an immovabtcsupport for the restc' The driver a now comes downonto the nailhead and forces said nail through the loose jaws k and I,which open outward accordingly, and the nail is driven into the materiallying on the now immovable rest a. As soon as the driver a has reachedits lowest point the eccentric f and its connecti ns release the grip onthe rod 1, and the teed-wheel s is then immediately caused to act by theco centric p, which is in such a position as to be just then commencingto lift; the eceentricconnectingrod 1), by which it raises the armhavingaspring-pawl at the end thereof, which pawl,when the arm (I isforced down,runs over the teeth a on the end of axis 1/, (see Fig. 1,)and this pawl engages with the teeth 11* on the axis 14, and sopartially revolves the said axis )1 and toothed wheel 1: on the endthereof, and thislatter again gives a partial revolution to the wheel s,against the milled or toothed edge of which the work is pressed, whichis thus fed forward aftereaeh nail has been driven in, the distanceapart at which it is desired to d rive the nails being regulated more orless by altering the position of the lower end of the rod 1) in the slot(1 of the arm (1, (see Fig. 2, and thus causes more or less travel ofthe arm q, and consequently imparting more or less fcedanotion to thewheel 21. By turning the screw s", Fig. 1, round the supports and feedregulating wheel s are drawn away from or moved toward the rest (6 andopening j, through which the nails are driven, and so regulates thedistance from the edge ofthe material at which it is desired to drive inthe nails.

If desired, an indicator or counter, 'lt, may be mounted, as shown inFig. 1, the main axis v passing through the top thereof, and so actirating the train of wheels of the counter, and thus showing the number ofnails used, as at each revolution of the axis 0 a nail is fed down anddriven into the work.

Having thusdescribed my invention, I claim as new and desire to secureby Letters Patent 1. In a boot-nail driving machine, the colnbination,with the plate 9, having the slot 1 and an aperture, 0, of the slide h,having the slot at an angle totheslot g, and also having the slottransversely to the slot y, substantially as set forth.

2. Ina boot-nail-driving machine, the combination, with the slide it,having the sloti therein tin-supplying one nail at a time under the naildriver, ofthe cam c, the plunger 1, the nail-driver a, the rockingnail-reservoir f, and the forked arm f, the said plungerarocking thenaitreservoir by means of said forked arm f substantially as set forth.

In a boot nail-driving machine, the conr bination, with a cam,c,nail-reservoirf nailfeed-regulating slide h, and slotted plate g, of atube, 0, plunger a, carrying the nail-driver a at its lower end andhaving the forked arm I' connected to its upper end for rocking thenail'reservoir, and the loose jaws k and I, kept closed by spring in,substantially as set forth.
